The issue of installing curtains on the windshield and side windows worries many car enthusiasts who strive for comfort on hot days or want to hide the contents of the cabin from prying eyes. However, the legislation of the Russian Federation establishes strict restrictions on the use of any obscuring elements that may obstruct the driver's view of the road space. Window tinting and the use of curtains is not the same thing from a legal point of view, but the consequences of their use in the front of the car are often identical.
The main problem lies in the light transmittance parameters, which are strictly regulated by the technical regulations of the Customs Union. If the rules for rear windows are more relaxed and allow complete blackout, then increased safety requirements are imposed on the windshield and front side windows. Violation of these standards entails not only administrative liability, but also an order to eliminate the malfunction, which actually means the immediate dismantling of accessories.
In this article we will analyze in detail the current GOST requirements, analyze the legality of using various types of sun protection and consider real scenarios of interaction with traffic police officers. Understanding the legal intricacies will help you avoid fines and disputes on the road, while maintaining an acceptable level of comfort in the car.
Regulatory framework and GOST requirements for light transmittance
The fundamental document regulating vehicle safety issues is GOST 33990-2016, which is harmonized with international standards. According to current standards, the light transmission of the windshield in the area visible to the driver should not be less than 70%. This requirement is aimed at ensuring maximum visibility, especially in poor light, fog or night conditions.
For front side windows, the requirements are similar: the light transmission must also be at least 70%. This means that the use of any additional films, coatings or curtains that reduce this indicator is a direct violation of technical regulations. Even factory tint can fade or become damaged over time, changing its physical properties.
The rear windows, in turn, can have any degree of shading, provided that the car is equipped with exterior rear-view mirrors on both sides. This important exception allows owners to use accordion shades or blinds on the rear window without risking a fine as long as they do not obstruct the view through the side mirrors.
⚠️ Attention: Technical requirements may be updated. Before installing any equipment, check the current light transmittance parameters in the official text of the Technical Regulations or consult with a certified center.
It is worth noting that the measurement of light transmittance is carried out with special devices - taumeters. The device must be certified and verified, and its readings depend on external conditions, such as humidity and atmospheric pressure. However, the presence of a curtain on the glass makes it impossible to take measurements without removing it, which is already a reason for demanding that the violation be eliminated.
Legal status of curtains and blinds on the windshield
The use of curtains on the windshield is strictly prohibited by current legislation. This is due to the fact that any object that blocks the driver’s view creates an emergency situation. According to paragraph 7.3 List of faults, prohibiting the operation of the vehicle, the presence of objects that limit the view from the driver’s seat is grounds for prohibiting further operation.
Blinds, even if they are moved to the side and not currently in use, are often mounted on suction cups or tracks, which themselves can be considered elements that impair visibility. The traffic police inspector has the right to regard the presence of fasteners on the windshield as a violation that requires immediate elimination.
The situation is aggravated by the fact that curtains are often made of opaque materials. Even partial lowering of such a curtain while driving completely blocks visibility, which can lead to serious consequences and classify the driver’s actions as creating a threat to traffic safety.
Why exactly 70%?
Research shows that when light transmittance decreases below 70%, driver reaction time to obstacles at dusk increases by 30-40%, which is critical for preventing accidents.
Is it possible to use curtains on the side front windows?
Regarding the front side windows, the situation is a little more nuanced, but the result remains the same for a moving car. If the curtain completely covers the glass and does not transmit light, its use is equivalent to 0% light transmittance, which grossly violates the norm of 70%. Therefore, you cannot drive with the curtains on the front doors closed.
Some drivers use so-called “mesh” or perforated materials, believing that they allow light to pass through. However, legally it is a fine line. If, during testing, the taumeter shows a value below 70% through the lowered curtain, a fine will follow. In addition, the mesh structure can create a moire or ripple effect, distracting the driver's attention.
The use of curtains is allowed only in a static position of the car. For example, when a car is parked in the sun and there is a child or animal inside, the use of curtains to protect against overheating is not prohibited. However, as soon as you drive away, the curtains must be retracted.
Table of permissible light transmittance values
For clarity, we present the main parameters that car owners must comply with. Compliance with these standards guarantees the absence of problems with technical inspection and traffic police.
| Glass type | Minimum light transmittance | Acceptability of curtains in motion | Acceptability of curtains in parking lots |
|---|---|---|---|
| Windshield | 70% | Prohibited | Allowed |
| Front side windows | 70% | Prohibited | Allowed |
| Rear side windows | No restrictions* | Allowed (with mirrors) | Allowed |
| Rear window | No restrictions* | Allowed (with mirrors) | Allowed |
*No restrictions - provided there are external rear view mirrors on both sides. If they are absent, the requirements for light transmittance can be equivalent to front windows.
It is important to understand that factory glass often already has a light tinting in the mass. If you plan to glue film or use overlays, you need to consider the overall effect. Light transmission is calculated as the product of the transmittance coefficients of glass and film.
Check the light transmittance of the glass when purchasing a used car - factory tinting may degrade over time and not meet the standards.
Fines for violating the rules of tinting and using curtains
The main article under which drivers are charged for improper tinting and using curtains is part 3.1 of article 12.5 of the Code of Administrative Offenses of the Russian Federation. It provides for the imposition of an administrative fine in the amount of 500 rubles. The amount seems insignificant, but the problem lies in the repetition of violations.
Traffic police officers can issue fines more than once. Although formally a fine cannot be issued for the same violation twice a day, in practice drivers receive an order to eliminate the problem. If you are stopped again an hour later or the next day with the same curtains, this may be considered a new offense.
In addition, in case of a serious violation, when the curtains completely block the view, the inspector may apply Article 12.5 part 1 (driving a vehicle in the presence of malfunctions), which also entails a fine or warning. In the worst case, when an emergency situation occurs, liability can be reclassified to more serious items.
⚠️ Attention: Payment of the fine does not relieve the obligation to eliminate the violation. You are required to dismantle the curtains immediately after stopping, otherwise the risk of another fine increases many times over.
There is also the risk of the vehicle being detained to remove the cause of the detention, although this rarely applies to tinting. However, if the driver refuses to remove the curtains and this interferes with the inspection or creates a threat, evacuation of the car is theoretically possible, but in practice it is usually limited to the requirement to remove the accessory on the spot.
Practical aspects and driving safety
In addition to legal aspects, the use of curtains on front windows poses a direct safety risk. Side visibility is critical when changing lanes, exiting secondary roads and driving through intersections. The curtain, even a translucent one, hides pedestrians, cyclists and other cars entering the “blind spot”.
At night, the contrast between the illuminated road and the darkened side window leads to rapid eye fatigue for the driver. The pupil does not have time to adapt to changing light conditions, which increases reaction time. This is especially dangerous in rain or snow, when visibility is already limited.
Curtain mounts can also become dangerous in the event of an accident. If the airbags deploy or there is a strong impact, the rigid elements of the curtain structure can break off and injure passengers. Plastic guides and metal arcs in this context turn into damaging elements.

Alternative solutions for sun protection
Given the strict restrictions, motorists have to look for legal ways to protect themselves from the scorching sun. One effective option is to use quality sunglasses with polarized lenses. They reduce glare from asphalt and other cars without impairing your view.
You can also consider installing athermal film. This is a transparent material that blocks ultraviolet and infrared radiation, reducing heating of the interior, but at the same time formally meets light transmittance standards (if the film is truly transparent). However, you need to be careful: some types of athermal have a purple or greenish tint, which may raise questions among inspectors.
For parking, an excellent solution is removable screens made of reflective fabric, which are installed inside the cabin on suction cups only when the car is stationary. They effectively reflect the sun's rays and do not violate traffic regulations when driving, as they are removed before the start of the trip.
The safest and most legal way is a combination of a thermal windshield (factory) and removable screens for parking.
Frequently asked questions (FAQ)
Is it possible to lower the curtains in a traffic jam when the car is barely moving?
No, formally, any movement of a vehicle on public roads is considered operation. If the car is in traffic, even at a speed of 5 km/h, all the requirements of traffic rules and Technical Regulations are in full force. Curtains on the front windows must be removed.
Is there a threat of removing rooms behind the curtains in 2026?
Removal of state license plates for tinting was abolished several years ago. Now only a fine of 500 rubles is applied. However, if the curtains completely block the view and create a clear threat, it is theoretically possible to detain the vehicle until the cause is eliminated, but the license plates are not removed.
Are curtains/blinds allowed inside the cabin if they are not glued to the glass?
The form of fastening (on the glass or on the door frame) is secondary. The main thing is functional use. If, while moving, the blinds are lowered and block the view or reduce light transmission below 70%, this is a violation. If they are raised and do not interfere with the view, there can be no complaints.
How to prove to the inspector that light transmission is normal with the curtain down?
Almost nothing if the curtain is opaque. The inspector is not required to carry out complex calculations. The presence of a thick curtain on the front window in itself is a sign of a violation of clause 7.3 of the List of faults. The only argument is to raise the curtain.
Is it possible to use magnetic curtains on the front doors?
You can use them in the parking lot. In motion - not if they reduce light transmittance below normal or limit visibility. The magnetic fastening is convenient because the curtain can be quickly removed, but this does not change the legal status.
